Roll Grinder Monitoring
For steel and aluminum mills, it is important to monitor the roll grinding process for the quality control.
The work rolls touch every surface of product that passes through a mill. Therefore, any pattern and lead lines on these rolls is imparted in the strip surface. Grinding chatter can lead to both 3rd and 5th octave mill chatter, which increases mill downtime and shortens the roll life.
The AS-250 SpectralMon system provides real-time feedback for the operator and managers to see the vibration signature being transcribed onto the rolls. Alarm limits can be set to control the acceptable vibration values during the different parts of the grinding cycles.
The AS-250 system interfaces with the grinding controls to get the roll parameters (diameters, depth of cut) and operating parameters (wheel load, traverse, normal force, overlap ratio, and aggressiveness).
The data of the grinding process is automatically saved by the roll id and the summary page is printed for quality control documentation.
